We have two kinds of databases: the one who has the graphical 
and geometrical data and the one who has the alphanumeric data 
related to the graphical data. The first one will be generated 
from the photogrametric digital system or from other graphical 
external files (like digitized plans, amateur photographs etc.). 
The second one will be handled with the DBMS ACCESS. Both 
databases will be linked and managed together by the GIS 
software Arc View 3.2, creating the information system. 
Objects are being built by linking spatial data (point, lines or 
polygons that are defined by geometry and topology) with non- 
graphic information in GIS. Coverage, also called as layer, is

the basic unit of storage in Arc/Info. In this study Arc/Info has 
been used for the establishment of topology of the coverage. 
Then the coverage has been imported to ArcView software. 
This software has been produced as a vector based GIS but also 
it has limited use of raster base data as well. In addition to 
several querying and analysis advantage, the result of these 
attributes. 
Digital data in Dgn format has 25 different layers. These digital 
data were transferred into AutoCAD format and number of 
these layers reduced in AutoCAD. The main layers used in this 
study are shown in figure 2.

Figure 2. Data Structure 
Also some of non-topographic information for feature 
(attributes) such quarter name, street name, door number, 
building functionality, basement, medium floor, roof, total 
floor, building condition, registration, building name, 
construction date, financer, architecture etc. were stored in the 
database table. Afterwards digital terrain model (DTM) of 
study area was being produced and captured with orthophoto in 
ArcView software. This model is shown figure 3. 
3D city modeling allows a person to interactively fly and walk- 
through a given urban space. This technology has already been 
applied to several cities worldwide; however, it has usually been 
implemented for limited sections of the city only. For these 
reasons 3D city model of study area was being produced. This 
model can be seen Figure 4.
